Hello,
I got a Hercules Fortissimo 7.1 sound card (CS4624 + two CS4294) but
snd-cs46xx driver supports only 6 channels (front, rear, center/lfe). The
surround output (7&8) is not supported - as seen in dsp_spos_scb_lib.c:
case DSP_PCM_S71_CHANNEL:
/* TODO */
snd_BUG();
break;
Tried to add a code for this, mostly copying the center/lfe code but I miss
some data:
- which slots (ACOSV_SLVx) should be used (maybe 10 and 12?)
- what are the channel_disp and fifo_addr values for
cs46xx_dsp_create_codec_out_scb() function
- what values should S71_MIXER_SCB_ADDR and S71_CODEC_SCB_ADDR be (maybe
0x1b0 and 0x1c0?)
